CHRISTIAN MIOHELSEN, OF ST. PAUL, MINNESOTA.

WINDOW-CLEANER.

SPECIFICATION forming part of Letters Patent No. 341,595, dated May 11, 1886.

. Application filed January 9, 1886. Serial No. 188,051. (No model.)

To (all? whom it may concern.-

Be it known that I, CHRISTIAN MIorinLsnN, a resident of St. Paul, in the county of Ranr soy and State of Minnesota, have invented an Improved \Vindow-Cleaner; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

My invention consists of an instrument by which awindow may be-washed, scrubbed, and wiped at one operation, and with great facility, rapidity, and efficiency. The essential features of the instrument are a water-receptacle, a scrubbing-brush, and a rubber or'wiper combined, the construction and operation of which I will now proceed to describe.

Figure 1 of the annexed drawings represents a side view of the instrument; Fig. 2, a front view of the same; and Fig. 3, a central vertical section thereof in a plane indicated by the line 1 1, Fig. 2.

Like letters designate corresponding parts in all of the figures.

The water-receptacle A, which forms the body of the instrument, is of oblong form, and may have any suitable or convenient shape, the nearly cylindrical form shown being entirely suit-able for the purpose. The dimensions of the receptacle may be regulated somewhat by the sizes of the panes of glass in the windows to which it is intended to be applied say, for ordinary household use, six or eight inches long and two inches in diameter. It may be made of sheet-tin or any other material desired. From its lower side a suitable socket, a, projects for receiving a handle, B, of a length suitable for the height of windows to be reached.

\Vith the construction shown the handle may be readily attached and removed, so that handles of different lengths may be applied, according to requirement. Any equivalent of the socket a, for attaching the handle, may 1 be employed.

The receptacle may have a filling-aperture, b, by which to pour water into the receptacle, to be closed or not by a stopper, as occasion may require. Such a filling-aperture may be convenient in some situations where water is not readily dipped up, and where it is desirable not to wet carpets or furniture in using the instrument; but for general practical and ready use the receptacle may be filled by dipping into a vessel of water and allowing the water to How into it through the dischargeopening 0 in the front side of the receptacle. This discharge-opening extends or may extend substantially the full length of the receptacle, the upper edge being nearly tangential with the upper edge of the receptacle, so that the receptacle may hold sufficient water for use below it when the instrument is held in the upright position shown in the drawings, in which position it must approximately beheld while using it in washing windows. The width of the aperture is suliicient to receive a brush, 0, therein, as shown. The brush is attached to a rod, (1, or other proper holder secured at the ends of the receptacle, so as to hold it fixed and firmin position. The brush, of course, properly extends about the entire length of the receptacle, so that it may scrub as great a width of surface as the size of the instrument will admit. Then around the edges of the oblong discharge-aperture is attached a rubber, D. This is most conveniently made of sheet india-rubber vulcanized and attached at the inner edge to the edges of the aperture, while the outer edge of the rubber extends to an even distance outward, so that the edges on the opposite sides and ends of the aperture may all fit close upon the flat surface of the window panes. The india -rubber is sufficiently thick to give considerable stiffness to the rubber, the ed gcs of which scrape over the surface of the glass. The bristles ot'the brush 0 should project somewhat farther outward than the edges of the rubber, so that they may operate efliciently on the glass, the rubber acting as a gage to the action of the brush.

In using the instrument it is first to have its receptacle filled as full as it willhold of water,

and it is then to be rubbed up and down,with' the brush and rubber pressed with more or 9 less force upon the glass, according to the condition of the same. The instrument is manipulated at the same time, so as to let the water flow out of the receptacle as fast as needed. \Vhile the brush serves to scrub the glass with the assistance of the water, the rubber assists I ture, 0, in one side, a brush, 0, located in or in in removing the dirt, and also wipes the glass front ofthe discharge-aperture, and a rubber comparatively dry as fast as washed; and or wiper, D, surrounding the (lischarge-aper- 15 when it is desired to wipe the glass even more ture and brush, substantially as and for the completely, after the instrument is passed over purpose herein specified.
